There was one beauty queen too many at Macy’s Thanksgiving Day Parade when uninvited Miss New York Davina Reeves crashed Miss USA Rima Fakih‘s float.

Reeves, wearing her Miss New York sash and crown, managed to claw her way onto Fakih’s float, and began enthusiastically signing autographs and waving to the crowd as the parade got under way.

Reeves hitched a ride for five blocks before Fakih’s horrified handlers managed to persuade parade organizers to boot her pageant rival off the float.

Our source said, “It was like a scene out of ‘Miss Congeniality.’ Miss New York somehow managed to get through security and get herself onto Miss USA’s ‘Pep Rally’ float.

“The real queen, Rima Fakih, kept her cool and her claws in. She gently spoke to Miss New York while Rima’s handler feverishly worked his iPhone to see why the uninvited extra queen was standing side by side with the reigning Miss USA,” the source said.

“Beneath the fixed smiles, handlers realized this wasn’t going to work as Miss New York began trying to hog the limelight. Finally, five blocks into the route, parade officials and the float manager politely asked her to leave, and she was helped down before disappearing into the crowd.”

Paula Shugart, president of the Miss Universe Organization, parent of Miss USA, said, “Miss New York wasn’t invited and nobody had any idea how she got on the float. She turned up in full pageant regalia, and she was initially asked to take off her crown so not to outshine Miss USA. Then, five blocks into the parade route, she was asked to leave. ”

Fakih, previously Miss Michigan, beat Austin native Reeves and a host of other beauties to be crowned Miss USA 2010 in May. The parade stunt was a final bow for Reeves, who will pass her Miss New York crown to the next beauty picked by the organization this weekend in Albany. Miss Universe pageant owner Donald Trump wasn’t available for comment. Reeves didn’t get back to us.
